I use openSuse 13.1 with Standard-KDE.
With Filemanager Dolphin you can connect via WiFi or USB.
With the Terminal you can get root access and/or use the midnight commander.
Everything works fine, but I have less experiences with other distributiones.
So in my opinion, you should use what is the best for you. ( I use suse since Version 4.4)

As sais the last link the developer have plans to port kdeconnect to sailfishOS. The android app works except for the notifications. You can copy files, control the mouse from the mobile or control media players on the computer from the mobile.
You can try the app from https://f-droid.org/repository/browse/?fdid=org.kde.kdeconnect_tp

You are right. Suse 13.1 works with Sailfish exellent. I tried Knoppix 7.2 - wich works partly, you get no possiblity to have a copy. Ubuntu Vers 12.04 allway updated works the same way as Suse 13.1, Mint 17 does'nt even exept Sailfish connections.

facepalm... thanks for your comment and correction i tried again with another usb cable and mtp works for me also!
I upgraded to mint17kde last week and since then used a broken cable that i thought to have already sorted out a while ago :P

I'll say none. (period) If you are ok enabling dev mode (which is not something your mom would do) and all the ssh/"hacker" stuff you won't have trouble with any distro.

From a mom/gradnma/non geek dad/grandpa POV the situation is a bit meh. And this applies to Mac also.

The best solution i found was Sailserver but it has a loooooong way until it becomes a mature application. I genuinely believe that jolla should have gone for an unlike/over WiFi solution for managing the phone from the beginning.

Linux lite 2.8 works fine for mounting my Aqua Fish and having access to Mass storage and SD card via mtp. Had some issues to get ssh working with Linux lite. Ssh works fine for me with Voyager X8, but in Voyager I had trouble to mount my Aqua Fish via mtp.
